High-mobility field-effect transistors fabricated with macroscopic aligned semiconducting polymers

Adv Mater. 2014 May 21;26(19):2993-8. doi: 10.1002/adma.201305084. Epub 2014 Feb 6.


A record high OFET hole mobility, as high as 23.7 cm(2) /Vs, is achieved in macroscopic aligned semiconducting polymers. The high mobility is insensitive to the polymer molecular weight. Polymer chains are aligned along the fiber to facilitate intrachain charge transport.

Keywords: conjugated polymer; fiber alignment; high mobility; intrachain charge transport; organic field-effect transistor.
